启动nginx报错
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
使用systemctl status nginx.service查看：
nginx.service - The nginx HTTP and reverse proxy server Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since Sun 2019-09-01 14:42:00 CST; 27s ago Process: 26735 ExecStart=/usr/sbin/nginx (code=exited, status=1/FAILURE) Process: 26731 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=0/SUCCESS) Process: 26729 ExecStartPre=/usr/bin/rm -f /run/nginx.pid (code=exited, status=0/SUCCESS) Sep 01 14:41:57 localhost.localdomain nginx[26735]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address alrea...use) Sep 01 14:41:58 localhost.localdomain nginx[26735]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address alrea...use) Sep 01 14:41:58 localhost.localdomain nginx[26735]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address alrea...use) Sep 01 14:41:59 localhost.localdomain nginx[26735]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address alrea...use) Sep 01 14:41:59 localhost.localdomain nginx[26735]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address alrea...use) Sep 01 14:42:00 localhost.localdomain nginx[26735]: nginx: [emerg] still could not bind() Sep 01 14:42:00 localhost.localdomain systemd[1]: nginx.service: control process exited, code=exited status=1 Sep 01 14:42:00 localhost.localdomain systemd[1]: Failed to start The nginx HTTP and reverse proxy server.

首先我们要弄清楚错误的原因是什么？百度了下原因，此错误是80端口被程序占用了。那么解决方法就简单了，强制关闭端口的占用就可以了，一个简单的命令就解决了。
sudo fuser -k 80/tcp #关闭占用80端口的程序
重启nginx服务就可以
